Country duo Sugarland motored to No. 1 on the Billboard 200 albums chart with The Incredible Machine. Sugarland’s latest effort beat out the new Kings of Leon album, Come Around Sundown, with 203,000 copies sold last week.

Watch Sugarland perform the “Wide Open” from the new album here. The video features vocalist/guitarist Kristian Bush on his Gretsch Irish Falcon.

A Gretsch 6120 Nashville model guitar autographed by Jennifer Nettles and Kristian Bush—better known as Atlanta-based country music super-duo Sugarland—will be auctioned on eBay between June 23 through June 30. The proceeds will go to support educational music programs sponsored by AthFest, Athens, Georgia’s long-running music festival.

The guitar was donated to AthFest by The Gretsch Foundation, an organization chartered by Savannah’s Fred and Dinah Gretsch to help promote music and arts education programs.

“When folks who understand the value of music as a way to enrich people’s lives work together, amazing things can be accomplished,” said Fred Gretsch.

The Gretsch Foundation donates Gretsch guitars to programs like AthFestAfterSchool, AthFest InSchool, and Keys For Kids. The guitars are decorated by major artists and/or signed by prominent musicians, and then auctioned off on eBay to raise funds. Over the past two years The Foundation has donated guitars signed by the members of R.E.M., Widespread Panic, and The Drive By Truckers.
